MSG91 Reviews & Product Details

At Cal Coast Bicycles, we rely on MSG91 for OTP verification, transactional SMS, and customer communication automation. The platform is stable and performs consistently, especially for time-sensitive messages like authentication codes.

From a UI/UX perspective, the dashboard is clean and functional. While it takes a little time to get used to, once familiar, managing templates, flows, and reports becomes straightforward.

The integration experience is one of the strongest points. We integrated MSG91 with our backend systems using APIs, and the documentation was clear enough for quick implementation without major blockers.

In terms of performance, message delivery is fast and reliable. OTPs are usually delivered within seconds, and we rarely face delays even during high traffic periods.

The pricing and ROI are reasonable compared to other messaging platforms. It reduces manual communication efforts significantly, which improves operational efficiency and saves cost in the long run.

There is also some level of intelligent routing and delivery optimization, which helps improve message success rates without manual intervention. Review collected by and hosted on G2.com.

The onboarding experience could be improved. New users may find sender ID setup, templates, and flow configuration slightly confusing at first.

Some advanced analytics and reporting features are limited. More detailed insights into delivery failures and performance breakdowns would help technical teams troubleshoot faster.

Support is helpful, but resolution time for complex issues can sometimes be slower than expected. Review collected by and hosted on G2.com.

We use MSG91 across multiple client projects at Ntiva, mainly for OTP authentication, transactional alerts, and WhatsApp notifications. The UI is fairly clean and easy to navigate once you get familiar with it. The Flow Builder is especially useful — it allows us to design automation visually instead of relying only on code.

In terms of integrations, connecting MSG91 with our internal systems and CRM tools was straightforward using APIs. The documentation is helpful, and most integrations work smoothly without major issues.

Performance-wise, message delivery is fast and reliable. OTPs are delivered within seconds, which is critical for user authentication flows. We also noticed stable uptime during high traffic periods.

Pricing is reasonable compared to other messaging providers. The ROI is clear for us because it reduces manual communication effort and improves customer response time. Review collected by and hosted on G2.com.

Some parts of the dashboard can feel slightly confusing for new users, especially when configuring flows or templates for the first time. The onboarding process could be more guided with step-by-step tutorials.

Also, while support is responsive, complex issues sometimes take time to resolve. More detailed error logs would make troubleshooting easier. Review collected by and hosted on G2.com.

We started using MSG91 in one of our eCommerce projects where we needed to send order updates and OTP verification messages to customers. Since we manage multiple Shopify-based stores at Velstar, having a reliable SMS solution is important for our operations.

From a UI/UX perspective, the platform is clean but takes some time to understand initially, especially while working with templates and flow setup. Once familiar, the flow builder becomes useful for building simple automation without much engineering effort.

In terms of integrations, MSG91 works well with our backend systems through APIs and was relatively easy to connect with our existing setup. Performance has been consistent, and delivery speed is generally fast, which is critical for OTPs and order notifications.

Pricing also felt reasonable compared to other providers we evaluated, and it provided good ROI since we use it across multiple client stores without significant cost overhead. Review collected by and hosted on G2.com.

The onboarding experience could be improved for new users. Some parts of the dashboard are not very intuitive at first, and understanding template setup requires trial and error.

Support is helpful, but response time can sometimes vary depending on the issue. Also, the system does not provide much AI-driven intelligence or smart insights, such as delivery optimization or engagement analytics, which could make the platform more advanced.

When errors happen in a flow, the debugging information is not always detailed enough, so troubleshooting takes additional time. Review collected by and hosted on G2.com.

As a Chief Technology Officer at Tablevibe, we use MSG91 mainly for sending OTPs, order confirmations, and occasional campaign alerts across our few partner restaurants. From a UI/UX perspective, the platform is fairly clean and structured once you get familiar with it. The flow builder is especially useful for setting up simple automation like order status updates without needing heavy development work.

In terms of integrations, we connected MSG91 with our backend ordering system via APIs, and it has been flexible enough to handle our use case. Performance has been reliable—message delivery is generally fast, which is critical for OTP verification and real-time order communication.

Another thing worth mentioning is the pricing. Compared to some alternatives we evaluated, MSG91 offered a more cost-effective setup for transactional messaging, which made the ROI reasonable for scaling across multiple restaurant clients. Review collected by and hosted on G2.com.

The initial onboarding experience could be smoother, especially for non-technical users. Some parts of the dashboard are not very intuitive at first, and template configuration requires a bit of trial and error. Also, when something fails in a flow, the error logs are not always detailed enough, which slows down troubleshooting.

From an intelligence standpoint, it would be helpful if MSG91 offered more built-in analytics or AI-driven suggestions (like delivery optimization or engagement insights) instead of relying mostly on basic reporting. Review collected by and hosted on G2.com.

Our software product uses MSG91 for login verification and alerts. What we found most beneficial is the speedy delivery of OTP, which makes the login process more seamless.

We found the integration aspect to be appealing as well. The initial setup was completed reading the documentation which does not take much time as connecting SMS API from the backend was easy. When we manage backend with Supabase then we did not face any major issues adding MSG91 here.

Furthermore, you can monitor which OTPs have failed or been sent, which is useful for troubleshooting – another good feature. Review collected by and hosted on G2.com.

The dashboard UI is not very friendly. Looking for some things takes a while, especially in the reporting section.

Although the delivery is mostly on time, there are delays that you will notice while doing OTP verification. In fact, they haven't always responded right away. In some cases, I have had to follow up.

The pricing structure is easy to understand, but the cost rises sharply with usage which makes long-term forecasting somewhat precarious. Review collected by and hosted on G2.com.

I work for a medium-sized e-commerce business (team of around 51–200 people), and we mainly use MSG91 for OTPs and order updates.

What I liked most was the speed of OTP delivery most of the time, it reaches users within 2–3 seconds. This means there are no hassles with the login or verification process. The dashboard isn't very complicated; even new users can quickly get to grips with it. We integrated with Shopify and Zoho CRM both integrations went very smoothly. Our developer didn't need much time to set up the API. Once, during one of our sales, traffic suddenly increased, but message delivery remained stable. This was important to us because, at that time, if the OTP failed, the conversion rate would have dropped. Review collected by and hosted on G2.com.

Although everything is generally working well, there are still some issues in certain areas. Occasionally, OTPs are delayed for some numbers, especially in remote areas. Although it's not a huge issue, it is noticeable. Another thing is that some of the reporting options on the dashboard seem a bit basic, if you want to carry out a detailed analysis, you have to export the data and view it separately. Support is generally fine, but it takes a bit longer to get a response at peak times.

I think it would be good if the support team's response time was a bit faster. Review collected by and hosted on G2.com.

We mainly use MSG91 for order updates, OTP verification and customer notifications. What we found most helpful was being able to manage multiple communications from one place - both OTPs and transactional SMS messages. This means we don't have to maintain separate services. The API integration process was smooth for us. The development team managed to set up the basic flow in a very short time. In particular, it has become easy to trigger order confirmation SMS messages. Another positive aspect is that deliveries are fast most of the time - customers receive updates quickly, which has led to a slight reduction in support queries. You can track issues by checking the logs on the dashboard, which is useful in practice. Review collected by and hosted on G2.com.

The user interface of the dashboard is not fully intuitive. Finding some options can take some time especially the first time around. The reporting section must be focused clarity. The delivery will not miss an OTP or notification that needs to be delivered urgently. Although, at times the delivery is getting delayed in most of the cases it’s good. At first the pricing was something we could manage. But as we started using it more and more we found it becoming expensive. The support team is helpful, but not always on time. I had to follow up on several occasions. Review collected by and hosted on G2.com.

We use MSG91 within our SaaS app for user verification and system notifications. What I like the most is the OTP delivery speed. Most of the time the users get the OTP within a few seconds. This helps to keep the onboarding flow smooth.

Integrating the API was easy. The SMS API setup was done in no time by our development team and the documentation is clear. You can look at the logs that show the SMS sent and failed from the dashboard.

Moreover, in addition to OTPs, we can also send transactional alerts (like account updates or payment confirmations) from the same platform, which has multi-use support. This means you will not even need to use a different tool, thus simplifying the workflow. Review collected by and hosted on G2.com.

At first, I found the dashboard to be very annoying. The interface is filled with many options but I do not need to select all options. The organisation in the reporting section should be a bit more clear and more organised.

Generally speaking, it is quick but may have delays. Messages may not reach the delivery channel (user’s mobile) which hampering OTP flow. User is unhappy and said code delivery was late.

In the beginning, it was affordable but after that, the price skyrockets as the long term planning doesn’t get easy when gets breakdown. The feedback you get may not be fast. You may occasionally have to follow up. Review collected by and hosted on G2.com.

The biggest advantage is their delivery success rate.

The OTP

failure rate is much lower than that of many other providers.

The API response time is very fast, which has significantly improved the user experience of our app. Review collected by and hosted on G2.com.

Their dashboard or admin panel is somewhat complex.

Occasionally,

it can be quite a hassle to find a specific transaction log.

Furthermore, it is not always possible to get an instant reply when chatting with the support team. Review collected by and hosted on G2.com.

MSG91 is easy to implement and integrate with our scheduling system. Pricing is affordable and transparent, which makes cost management straightforward. SMS delivery is reliable and messages usually reach users on time, which is important for reminder notifications. The platform is simple to use on a daily basis. Customer support has been great overall. Karan was very responsive and helpful whenever we needed assistance. Review collected by and hosted on G2.com.

Sometimes webhooks do not get delivered properly, and in a few cases it is not very clear why an SMS failed. The error details could be more descriptive. That said, some of these issues can also be due to carrier-side problems, so it is not always in MSG91’s control. Review collected by and hosted on G2.com.
